热风炉的操作设备主要是各种阀门。阀门的作用有两种:一是起切断作用的;二是起调节作用的。阀门按其用途和工作条件的不同,选择不同的材质和结构形式。
  Hot blast stove operation equipment is mainly a variety of valves. There are two functions of the valve: one is to cut off; the other is to regulate. Valves are made of different materials and structures according to their different uses and working conditions.
  (1)热风阀。热风阀是一个耐高温的闸板阀,每座热风炉一个,安装在热风出口与热风主管之间的热风短管上,用于隔断热风炉和热风管道。为了延长热风阀的使用寿命,热风阀除强化冷却外,还将阀饼镶衬耐火材料。
  (1) Hot air valve. The hot air valve is a gate valve with high temperature resistance. Each hot air stove is installed on the hot air short pipe between the hot air outlet and the hot air main pipe, which is used to isolate the hot air stove and the hot air pipeline. In order to prolong the service life of the hot air valve, the hot air valve not only strengthens cooling, but also lining the valve cake with refractory material.
  (2)燃烧阀。燃烧阀(顶燃式热风炉)的结构和热风阀基本相同,只是用途有所区别,安装在热风炉燃烧器与煤气和助燃空气之间的短管上。主要用于热风炉送风期使热风炉和煤气及助燃空气管道隔断。
  (2) Combustion valve. The structure of the combustion valve (top-burning hot blast stove) is basically the same as that of the hot blast valve, but its use is different. It is installed on the short pipe between the burner of the hot blast stove and the gas and combustion-supporting air. It is mainly used for separating the hot blast stove from the gas and combustion-supporting air pipes during the air supply period of the hot blast stove.
  (3)烟道阀。烟道阀一般采用闸板阀,在球式热风炉上由于受安装位置的限制,没计院大多数都设计为“大头阀”(盘式曲柄阀),主要用于热风炉送风期(或焖炉时)使热风炉和烟道隔断。
  (3) flue valve. The flue valve usually uses gate valve. Because of the limitation of installation position, most of the flue valves are designed as "big head valves" (disc crank valves), which are mainly used to isolate the hot air stove and flue during the air supply period (or baking time) of the hot air stove.
  (4)煤气切断阀。煤气切断阀一般采用闸板阀,安装在煤气管道上,主要用于热风炉在送风期使热风炉和煤气管道彻底隔断。
  (4) Gas shutoff valve. Gas shut-off valves generally use gate valves, installed in gas pipelines, mainly used for hot blast stoves in the supply period so that hot blast stoves and gas pipelines are completely separated.
  (5)空气切断阀。安装在与燃烧器连接的助燃空气管道上,主要用于热风炉停止烧炉后使热风炉和助燃空气管道隔断。
  (5) Air shutoff valve. The utility model is installed on the combustion-supporting air pipeline connected with the burner, which is mainly used for separating the hot blast stove and the combustion-supporting air pipeline after the stopping of the hot blast stove.
  (6)煤气调节阀。安装在与燃烧器连接的煤气支管上,该阀电动控制。当煤气燃烧阀和煤气切断阀全开后,通过调节阀来调节热风炉在燃烧期的煤气量。
  (6) Gas regulating valve. The valve is installed on the gas branch pipe connected with the burner and is electrically controlled. When the gas burning valve and the gas cutting off valve are fully opened, the gas quantity of the hot blast stove during the combustion period is adjusted by adjusting the valve.
  (7)空气调节阀。安设在与燃烧器连接的助燃空气管道上,该阀电动控制。用以调节热风炉燃烧时所需的助燃空气量。

  (7) Air-conditioning valves. The valve is mounted on the combustion-supporting air pipe connected with the burner and is electrically controlled. It is used to regulate the amount of combustion-supporting air needed for hot blast stove combustion.
  (8)混风调节阀。安装在冷风管道与热风管道的连接管上,它与一台切断阀(又叫冷风大闸)配套使用,用来调节风温。
  (8) Mixed air regulating valve. Installed on the connecting pipe between the cold air pipeline and the hot air pipeline, it is matched with a cut-off valve (also known as the cold air gate) to regulate the air temperature.
  (9)冷风大闸。冷风大闸是安装在靠近热风总管的混风管道上,是切断热风总管和冷风管道连通的阀门。另—个作用是:避免当冷风管道内压力降低时热风(倒流时则是煤气)进入冷风管道。
  (9) Cold air gate. The cold air gate is installed on the mixing duct near the hot air main pipe, and is a valve to cut off the connection between the hot air main pipe and the cold air pipeline. Another function is to avoid the hot air (gas) entering the cold air pipeline when the pressure in the cold air pipeline decreases.
  (10)倒流阀。高炉以前都是通过烧热的热风炉倒流休风,这既不安全,又易损坏热风炉高温区砌砖和堵塞蓄热室格孔。
  (10) Backflow valve. Blast furnaces used to be backflow through hot stoves, which is not only unsafe, but also easy to damage bricklaying in high temperature zone of hot stoves and plugging the grid holes of regenerator.
  (11)冷风阀。冷风阀每座热风炉一个,安装在向座热风炉送风的冷风管道上,热风炉烧炉时使热风炉和冷风管道隔断。
  (11) Cold air valve. The cold air valve is installed on the cold air pipeline for feeding air to the towering hot air stove. When the hot air stove is fired, the hot air stove and the cold air pipeline are separated.
  (12)冷风均压阀。冷风均压阀安装在联络冷风阀两侧的冷风均压管上,热风炉送风需要开冷风阀时,先开冷风均压阀使冷风阀的两侧压力达到一致,冷风阀在没有压差的情况下开启。
  (12) Cold air pressure equalizing valve. The cold air pressure equalizing valve is installed on the cold air pressure equalizing pipe on both sides of the connecting cold air valve. When the hot air stove needs to turn on the cold air valve, the cold air pressure equalizing valve is first opened to make the pressure on both sides of the cold air valve reach the same level, and the cold air valve is opened without pressure difference.
